12.3.2
(Group 1 Address) VLAN Group
12.3.2.1
AVTCL – VLAN Type Code Register Low
IC Address: h028; CPU Address: h0100
Accessed by CPU and IC (R/W)
12.3.2.2
AVTCH – VLAN Type Code Register High
IC Address: h029; CPU Address: h0101
Accessed by CPU and IC (R/W)
12.3.2.3
PVMAP00_0 – Port 0 Configuration Register 0
IC Address: h02A, CPU Address: h0102
Accessed by CPU and IC (R/W)
In Port Based VLAN Mode
This register indicates the legal egress ports. A “1” on bit 3 means that the packet can be sent to port 3. A “0” on bit
3 means that any packet destined to port 3 will be discarded. This register works with registers 1 to form a 10 bit
mask to all egress ports.
In Tag based VLAN Mode
This is the default VLAN tag. It works with configuration register PVMAP00_1 [7:5] [3:0] to form a default VLAN tag.
If the received packet is untagged, then the packet is classified with the default VLAN tag. If the received packet has
a VLAN ID of 0, then PVID is used to replace the packet’s VLAN ID.
12.3.2.4
